FEEDING AND REMOVING APPARATUS FOR FURNACES.

Specification of Letters Patent.

' Patented Nov. 4, 1919.

Application filed May 17, 1917. Serial No. 169,202.

To all whom, it may concern:

lie it known that I. lh'omr: L. McGi'nuc, citizen of the l nitcd States. residing at Dennison. in the county of Tuscarawas and State of Ohio, have invented certain new and useful Improvements in l ecding and Removing Apparatus for Furnaces, of which the following is a specification.

My invention relates to heating apparatus and more particularly to means for mechanically feeding the fuelthereto, removing the ash, and regulating the drafts.

()ne of the objects is to provide mecha nism of this class adapted primarily to permit a heating apparatus or )lant located in the basementto be operated from living rooms or other central point of the building and which will prevent dust and dirt.

Another object is to provide novel and efficient means for controlling the operation of the different mechanism.

Generally stated. the invention comprises power means, combined with the furnace structure, and suitable conveyors, shafts, drive, connections, and control means whereby the furnace may be entirely operated and regulated from a. distant point.

One preferred construction of the invention is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of a furnace embodying my invention, the furnace being partly broken away,

F ig. 2 is a front elevation of the" same partly broken away and showing the controlling means in detail, and

Fig. 3 is a detail view of one of the belt shifts employed. 4

Referring more particularly to the drawings the numeral 2 designates the shell of a furnace having a fire pot 3 and grate 4.

A drive shaft 5 is situated above the furnace and preferably hung from the ceiling by hangers (Sand is driven by a suitable power such as the motor 7 or may be manually turned by means of the chain and sprocket mechanism 8.

The fuel is stored in a hopper 9 having an inlet entering a conveyer casing 10 having a conveyer 11 trained about pulleys 12, 13 and 11 therein. The pulley 11 is mounted on a shaft 15 and is connected with the drive shaft 5 by a belt 17 trained over pulleys 16 and 18. An idler pulley 19 is mounted adjacent the pulley 18 for a purpose to be described. The conveyer casing 10 cnters the tire-pot and has its inner end closed by a flap door 20 and also has a slide door 2.1 to cutoff the coal supply. the slide door 2]. being operated by a melilber 2- having a terminal 23 atany desired place.

Located within the tire-pot is a rocking grate 1 which is operated by suitable crank and link mechanism Z-l connected to shaft mounted in hearing 26 on support 27 and driven by belt 23 trained about pulleys :29 and 30. The pulley 30 is keyed to the shaft 5 and has an idler 31 mounted adacent thereto.

The bottom of the fire-pot slopes downwardly to the rear forming a chute and converges to the exit 32 entering the conveyer casing 33 which terminates in a suitable outlet 34 which is preferably located at the exterior of the building. A conveyer 35 is trained about pulleys 3t) and 37 within the casing 33 and is driven by a belt 38 trained about the pulley 39 on shaft 40 and pulley 41. The pulley 41 is keyed on the shaft 1 and has an idler 42 mounted adjacent thereto.

A sliding out off door 43 is mounted in the exit 32 and operated similar to door 21 in casing 10 by a member 41 having termirial-l5. Slidably mounted in hangers 46 are belt shifts 47 having shifting arins 18 and flexible connecting members 49 secured to each end thereofand trained over sheave wheels 50 and connected to cranking wheels 51.

A belt shift 17 is provided for each of the belts 17, 28 and 38 and is adapted to shift the respective belts by a turn of the crank 51 onto their respective idlers thus making the desired parts inoperative.

The motor 7 supplying power to the main shaft 5 is controlled by a switch 52 adjacent the cranking wheels 51.

The draft entering the fire-pot 3 is controlled by a suitable door 53 adapted to he raised or lowered by a flexible member 51 secured to crank 55.

The operation of my device is as follows :T he motor is started and the suitable crank 51 is turned to throw belt 17 on the idler 19, the sliding door 43 is then raised by grasping the terminal 45 of member lt and the ash will enter the casing 33 and be carried away by the conveyer 35. The ash having been removed, the door 43 is therewith of a sep belt-shifting device, for,

compartment and connected with each of lowered and suitable cranking wheels 51 are turned to throw belts 28 and 38 on their respective idlers and belt 17 from idler pulley 19 to pull y 18; the conveyer 11 will then be in operation and the slide door 21 is then raised by grasping the terminal 23 of the member 22 permitting the fuel to enter the fire-pot.

It will be obvious a control system and the mechanism for carrying-it out that will eliminate all the objectionable labor for caring for a furnace. f

It will also be obvious that various changes in construction-may be made from time to time to accommodate the many dif-' ferent forms of furnaces and although I v have shown and described a preferred form of my invention I donot wish to be limited. .to that construction since the above and other minor changes in construction may spirit of my invention pended claims.

Having'thus described-my invention, Iclaim is: i
